We now have videos of this happening. 100% reproducible. We are trying to get through to Adobe with the videos. Here are steps to reproduce:

1. Uninstall Adobe Creative Cloud

2. Install Backblaze, notice that a folder is created at the very top of drive named .bzvol (/.bzvol/README.txt exists)

3. Install Adobe Creative Cloud -> They remove /.bzvol/README.txt at time of install (along with other files)

This is bad. Adobe really needs to fix this. They really should not be removing other program's files. Remember, this is 100% reproducible so just do not install Adobe Creative Cloud and do not install any updates.

So I’m in the middle of finalizing a project today, Feb 11, 2016, in inDesign CC 2015, MAC OS 10.10.5, and out of the blue Creative Cloud starts updating, I get some ridiculous error message, then another one, and it shuts down inDesign. It all happened in about 10 seconds, and I didn't even have a chance to see what the error code was, and something about working offline I think. Then literally half my work file folders are gone from my hard drive, GONE! Not just the inDesign files, but all the fonts, images, text files. I don’t use or sync my files to Creative Cloud, they only reside on my hard drive so what the hell just happened! How do half my files just disappear, I wasn’t doing anything except working on a project using inDesign like I have a million times with no issues.

Can someone please explain to me what just happened. Literally lost folders of previous work projects and many major current projects that were practically finalized and now will have to try to recreate for my clients. I don’t use the cloud because of the issues and all the files were on my computer only — HOW DOES THIS HAPPEN!

I’ve read about this being an issue about a year ago, so why is it still happening now and not been fixed! I doubt I will get any kind of response, but if someone could possibly explain this to me I would really appreciate it, because this is crap especially when people are forced to use the apps this way and no longer actually purchase the software.

Thanks in advance for any response or insight into this issue at all, and if there is any chance of getting my Project Folders back, lost just a ridiculous amount of work. And yes I know about backing up files, that isn't the issue here, it's a serious issue with CC if my files can just disappear for no apparent reason. I back up files a couple times a month, but completely lost all current job folders.

Thanks for bringing this up, could you please help us with the log files? We would like to get more information about it, here is Adobe Creative Cloud Log Collector Tool which you may use to collect the log files.

I'm am seeing this same error on my Macbook Pro and my finace's Macbook Air. There is now another "Macintosh HD" listed in Backblaze settings. If I select it, I get a message saying that it will replace my original drive, which I'm assuming isn't something I want to do. I'm also using Creative Cloud so this is mostly likely the cause.

Thanks Steve. Apparently Adobe has stopped/pulled the recent update to the Creative Cloud Desktop app (version 3.5.0.206 released on 2/11/2016).

In response, the CC 2015 direct download links have been reverted back to the previous version as well – version 3.4.3.189 from 12/21/2015 has now been restored and can be downloaded there. So it's possible to return to the prior release manually by installing the older version over the newer one, for whoever wants or needs to.

(You can see the release you're running by going to the Settings "gear" icon at the upper right of the CC Desktop app, and then selecting Preferences.)

Steve's right on. Neither of us are employed by Adobe; we're just trying to help out other users here.

There was a statement given in the Ars Technica article that Steve shared:

An Adobe spokeswoman issued a statement that read: "We are aware that some customers have experienced this issue and we are investigating in order to resolve the matter as quickly as possible. We are stopping the distribution of the update until the issue has been resolved."

Regarding the CC direct links, please make sure you carefully follow the download instructions given on that page (before clicking on the links)... Doing so is required by Adobe's servers; otherwise you will receive that "denied" message.

Just to go on the record, I too wound up with half of my client folders removed from my hard drive this morning. You see, as some others, I had my "Clients" folder labeled with a space before the first letter of the folder so that it would sit at the top of my directory. The folder itself was not deleted, but as I mentioned about half of the client folders inside that folder were MIA.

At first I attributed it to the fact that we had a neighborhood power failure last night (Thurs), but after reading several posts on the 'disappearing' files, I'm starting to think it had nothing to do with the power failure. I spent most of the day (Friday) searching my computer for the files and ultimately restored the client folders from a backup. This unfortunately did not take care of the work I lost yesterday that was scheduled to be backed up last night. I knew I didn't want to move to the 'cloud', and if in the end, it's determined that this is the cause for the disappearing folders and file, just re-affirms my original opinion about using the service.

Sorry to hear about the headache and inconvenience of lost work... It's always a huge pain when that happens.

The bug is unfortunate, but has nothing to do with "the cloud" in particular. It appears to just be a buggy desktop software update, that happened in the CC desktop app.

Bugs are not new in Adobe software, nor in any software anywhere. Software is written by humans, and humans are fallible, thus bugs happen. 100% certifiably bug-free software of any level of complexity has never existed in the history of computers.

Not trying to make excuses for Adobe. Obviously bugs slip through, as they did back in the Creative Suite days. The upside of CC is that we get product updates and new features faster and more regularly, but the flip side is that we may see bugs faster too.

In any event, no doubt the Adobe engineers are upset this happened and working hard to get it fixed just as fast.

Thanks imksn. That clarifies it. Funny thing is I haven't seen any error messages or lost any work... don't really use the autosave feature. Wasn't even aware of the problem until macrumor talked about it.
